Good morning, PB. Throughout my life, I have always loved history. As I grew older, my interests took a different route. I have recently been bitten by the Church history bug. I finished Bruce Shelley's "Church History in Plain language" and am now burning through Justo Gonzalez's "Story of Christianity." While these have been a fascinating journey, I need more penetrating reads. What are some of your favorite monographs on a specific time, event, or person in Church history? Thanks.
